Choose a shrink label printing ink need to understand
There are a lot of shrink label printing inks. How to choose the proper ink type? The ink supplier must first understand the following information.
â— Printing Methods Flexographic printing and gravure printing are mainly used for shrink label printing. The ink printability of different printing methods is different.
â— Container shape The shape of different containers has different requirements for the shrinkage of the material.
â— The printing materials with different printing materials such as PVC, OPS, OPP, PETG and other materials have different requirements for the ink.
â— Storage and Transportation Environment of the Product During the production, transportation and sales of the product, what happens to the container, how much friction coefficient is required, what is the temperature and humidity environment, and whether there are special requirements (shrinking labels for beer and beverage products Need good ice water resistance) etc.
Only after understanding the above factors can we select suitable inks from the aspects of shrinkage, adhesion, and ability to release residual solvents (ability to quickly dry at lower temperatures).
â— Shrinkage This is the primary consideration when selecting heat-shrinkable label printing inks. Because different products have very different requirements for shrinkage. High shrinkage products require a shrinkage of 60% to 70%, and low shrinkage rates of only 10% to 20%. The shrinkage properties and applications of different types of inks are shown in Table 1.
â— Adhesion When printing and rewinding, ink layers will often come in contact with each other if poor adhesion inks are used. Then, problems occur when the product is in contact with the ink layer. The most common problem is adhesion. In general, if the ink does not adhere well, you can use a method to increase the oven temperature. However, heat-shrinking materials are sensitive to temperature and cannot increase the temperature to increase ink adhesion. For the moment, the best adhesion inks are solvent inks and cationic UV inks. Water-based inks and free-radical UV inks have relatively poor adhesion due to their own raw material limitations.
• Residual Solvents National standards now have fairly stringent standards for residual solvent. Some printing plants set the drying temperature higher during the drying process of the ink in order to make the solvent evaporate faster, but this would cause the material to shrink in advance. Therefore, excessive heat cannot be applied to the shrink label during printing. This requires finding a balance between printing conditions and drying conditions.
In addition, printers must also rigorously test the heat shrink film and ink compatibility before choosing the right ink for a particular heat shrink label.
